This example renders a world map using D3.js and SVG, showing country boundaries as light blue shapes with white strokes. It loads GeoJSON world map data from a remote repository and applies a Mercator projection to convert geographic coordinates into screen positions, with the map centered on the canvas. The visualization demonstrates key D3 features such as `d3.geoMercator`, `d3.geoPath`, and loading external data via `d3.json`, alongside ES6 module imports from a local file. The map is drawn by binding the GeoJSON features to SVG `path` elements, with styling applied via inline attributes.
